Abstract

The invention discloses a waterborne polyurethane coating material capable of preventing neutron radiation and a preparation method of the waterborne polyurethane coating material, and belongs to the technical field of coating materials. The waterborne polyurethane coating material capable of preventing the neutron radiation is prepared from the following components in parts by weight: 30 to 50 parts of waterborne polyurethane emulsion, 3 to 10 parts of graphene, 10 to 20 parts of rare earth oxide, 10 to 20 parts of boron carbide, 5 to 10 parts of nano aluminum oxide emulsion, 1 to 2 parts of a waterborne dispersing agent, 1 to 2 parts of a waterborne defoaming agent, 1 to 2 parts of a waterborne wetting agent, 1 to 2 parts of a waterborne flatting agent, 0.5 to 2 parts of a waterborne suspending agent and 2 to 3 parts of a waterborne thickening agent. Waterborne polyurethane prepared by the invention has excellent mechanical performance and excellent bonding performance, and can be added into inorganic filler capable of preventing the neutron radiation in a large proportion.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a neutron radiation-resistant waterborne polyurethane coating and a preparation method thereof. Background technique [0002] With the development of nuclear power industry, many nuclear reactors need to be built. There are corresponding protective layers, shielding layers, and reflective layers inside the current nuclear reactor, which can prevent neutrons from leaking out when the atomic nucleus is working normally. However, if an abnormal accident occurs in a nuclear reactor, a large amount of neutrons will leak out, especially when a lethal neutron flow occurs under certain circumstances, these leaked neutrons will bring great harm to humans and the environment . Neutron radiation is more destructive and dangerous than gamma rays in nuclear radiation, so the protection against neutron radiation is more important. [0003] At present, heavy metals and transition metal oxid...
